LANTERN.

SPECIFICATION forming part of Letters Patent No. 718,105, dated January 13, 1903. Application filed December Z6, 1901. Serial No. 87.301. (No model.)

To a/Z whom, it motycmtccrn: p

Be it known that I, BURTON J. DOWNING, a citizen of the United States, residing at Antelope Springs, in the county of Mineral and` State of Colorado, have invented a new and useful Lantern, of which the following is a specification.

This invention relates to certain improvementsin lanterns of that class in which an ordinary lamp-chimneyis secured to a base carrying acandle or burner, and has for its principal object to provide an improved means for holding the chimney firmly in place and for effecting the release and removal of the chimney without touching the same with the hands.

A further object is to provide means for regulating the supply of air for the support of combustion and to provide for the locking of the draft-regulator in adjusted position by connecting the sameto the chimney clamp and support.

With these and other objects in view the invention consists in the novel construction and arrangement of parts hereinafter de scribed, illustrated in the accompanying drawingsfand particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of a lantern constructed in accordance with my invention. Fig. 2 is a sectionalelevation of the same. Fig. 3 is a sectional elevation of the lower portion of the lantern, taken in a plane at right angles to that indicated in Fig. 2. Fig. 4 is an inverted plan view of the base portion of the lantern.

The base-plate 10 is circular in form and is provided with a peripheral liange 11, preferably formed by bending up the outer edges of the plate to form an annular ange, and then bending such ange outwardly and downwardly to apoint in the same horizontal plane as the bottom of the base-plate 10, the edge portion of the flange being then bent inwardly to form a smooth supporting edge.

In the base-plate are a number of perforations l2, through which air may pass to support combustion, and to the central lower surface and the base-plate is pivoted a metallic strip 13, which may be 'turned on its4 Apivotpin 19 to cover any desired number of perfof rations, and thus regulate the quantity of air supplied to the lantern. The ends of the strip are provided with upwardly-bent portions 14 and l5, which are inclined toward the center of the base in order to keep the end portions of the strip in frictional contact with the periphery of the base-plate. At the extreme ends of the strip are hooks having downwardly-bent bills 16 and 17, respectively, which are adapted for engagement with the chimney-clamping device, the latter serving to hold the strip rmly against the bottom ot' the base and prevent accidental turning of the same to alter the quantity of air passing through the pertorations 12. In some cases this base-plate may also be provided with an annular flange 18, to which maybe fitted a chimney of smaller' diameter than the baseplate.

The pivot stud or pin 19 of the strip 13 eX- tends through the plate 10 and serves as a means ot securing a candle-socket 20, the pin passing Ithrough the lower portion of the socket and through a washerjlQ' and its upper end being upset in order to secure the parts together. In order to provide an auxiliary support for the candle, I employ a vertical rod 30, having inwardly-bent arms 31 and 32, the lower of which has a terminal loop or eye 33, extending around the pivot-pin 19 ata point between the plate 10 and the lower surface of the socket 20. The upper arm 32 has a larger terminal loop 34, adapted to surround the canl die and hold it against accidental displacement.

The device for holding and clamping the chimney 40 comprises an upper spring-clamp 50, preferably formed of wire and adapted to partially encircle the upper portion of the chimney.V At. a point about .midway of its length the wire is bentto formfa 4plurality ot' spring-coils 51, which may serve asahandle in manipulating the device and which act also to increase the elasticity of the clamp in order that the latter may bind more firmly against the chimney and adapt itself to chimneys ot varying size.

The two arms of the clamp extending from the coils 51 are provided with eyesZand 53, which are arranged `at points diametrically opposite a chimneybei'ng clampedfn place, and extending between the clamping member and the hooked ends of the strip 13 are con- IOO necting-rods 6() and 70, which may be outwardly bowed to follow the contour of the chimney. At the upper end of the rod are eyes 6l and 71 for engaging the eyes 52 and 53, respectively, of the clamp 50. At the lower end of these rods are loops 62 and 72, respectively, adapted to engage the hooks 16 and 17 on the pivoted strip 13. The rods maybe movably connected to the clamp 50, as shown, or they may be rigidly secured thereto.

/Vhile the spring-coils 51 may be employed as a handle for carrying the lantern or for ef fecting the removal of the chimney from the base, I prefer to employ a carrying-bail 80, provided with eyes 8l and 82 for engaging the eyes 52 and 53 by the clamp 50.

The clamp when contracted is of a diameter less than the diameter of the top of the chimney and when in chimney-.engaging position is slightly spread and irmly holds the chimney in place when the rods GO and 70 are in engagement with the lower hooks. When it is desired to remove the chimney, downward pressure is exerted on the clamp, causing a downward and spreading movement of the connecting-rodsrO and 70, the loops 62 and 72 of the latter being automatically disengaged from the hooks 16 and 17 of the base. By raising the clamp either by means of the bail SO or the spring-coils 5l the clamp is allowed to contract and engages with the aring upper portion of the chimney Without the necessity ot` touching the same by the hand, this being a desirable feature when the chimney has become heated from the flame. The chimney maybe readily replaced andthe clamp again pressed down until the loops of the connecting-rods can be engaged in the hooks 16 and 17. In some cases, as where a chimney having a non-Haring top is employed, the clamp may possess sufiicient inherent elasticity to bind against the upper portion of the chimney to permit the removal of the chimney by means of the clamp.

Vhile the construction herein described, and illustrated in the accompanying drawings, is the preferred form of the device, it is obvious that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

I-Iaving thus described the invention, what I claim is- 1. A lantern comprising in combination, a base, a globe, an elastic clamp partially encircling the upper portion of the globe, and means for detachably securing the clamp to the base, the downward movement of the clamp serving by contact with the chimney to spread said clamp and more securely hold the saine against the chimney.

The combination et the base, a chimney, a spring-clampv encircling the chimney and connected to the base, and a carryipg-handle connected to the clamp and serving as a means for carrying the lantern and also as a means for det-aching and securing the clamp to the base.

3. A lantern comprising a base, a chimney having a Haring top, a spring-clamp adapted to partially encircle the chimney at a point below the top, said clamp being movable both independently ot' and with the chimney, and of a diameter when contracted less than the diameter of the top of the chimney, and means for detachably connecting said clamp to the base.

4. The combination with a lantern having a baseplate and chimney, of a chimney clamping and removing device movable both independently of and with the chimney and comprising a pair of elastic arms having an integral spring-coil forming an operatinghandle, said arms being adapted to partially encircle the chimney and serving as a means for clamping the same in position and for raising the chimney from the base and for carrying the same independent of the base.

5. A clamping devicecomprising a clamp having a coiled spring projecting outwardly therefrom, and connecting-rods attached to said clamping member and provided with means for detachably engaging a supporting-base, the clamp in moving downward to engaging position being spread and firmly clamped to the chimney.

6. A clamping device comprising a clamp having a spiral coil projecting outwardly therefrom, said clamp being provided with loops at its opposite sides, and connecting members attached to said loops and adapted to detachably engage a supportingsbase.

7. A lantern having a base-plate provided with a plurality of perforations, an auxiliary plate revolubly mounted on said base-plate and provided with upwardly-extending hooks at its opposite ends, and chimney-clamping means adapted to be connected with said hooks.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

BURTON J. DOWNING.
